Why RIQAS Point of Care?
About RIQAS Point of Care
How it Works
Samples are regularly distributed to all participating sites. These are analysed in the same way as a patient sample and the results returned to RIQAS within a set time.
Participants are informed of their analyser performance via an electronic report. Satisfactory and unsatisfactory performance is highlighted using a traffic light system allowing instant identification of any issues, a detailed breakdown of performance may be obtained if further information is required. With time, an overall picture emerges showing whether results are consistently accurate and reliable or whether there may be an underlying analyser and/or operator issue.

Importance of Quality Assurance
Quality assurance is an essential aspect of any clinical/diagnostic testing service and is aimed at ensuring the accuracy and reliability of patients’ results. The right result allows the right clinical advice to be offered in a timely manner. Quality assurance operates at two levels:Internal Quality Control
Internal Quality Control includes operator training/ competency assessment, analyser/ test system maintenance, and adherence to policies/ processes. Whilst some point of care analysers include inbuilt quality checks, cross-check analysis against samples with known levels provides immediate assurance and evidence that a patient’s result is safe to report.External Quality Assessment
External Quality Assessment involves analysis of samples with unknown levels that have been distributed by an external organisation. Participants are informed how their results compare with other participants, hence providing independent evidence of performance. Increasingly, participation in an external quality assessment scheme is becoming a mandatory requirement where health and healthcare services are being provided.
EQA provides assurance to both staff and customers that testing provides accurate and reliable results.

When you have an infection, it’s important to receive the correct diagnosis in order to access appropriate treatments. Misdiagnosis can not only lead to the prolonging of the infection, but could also prove detrimental to your long-term health, such as if you become resistant to certain anti-biotic strains through mistaken prescription.
Throughout this month, we’ve been highlighting how the Randox clinical product range can assess the impact of infection. The RX series’ dedicated testing panel comprises of IgA, hsCRP and ASO which are also available for third-party use. The extensive QC range caters for assessment of infectious disease testing in both liquid and lyophilised formats.
The Randox range of third-party reagents enables the clinical analysis of 113 different analytes with comprehensive range measurements and excellent correlations to reference methods.
IgG (the most abundant antibody) and IgM (the first antibody made in response to infection) can be used in the diagnosis of Dengue Fever. This is significant as more than 40 % of the global population, in more than 100 countries, are at risk of the Dengue Virus.
IgA is an antibody that lines the mucous membranes lining the mouth, airways and digestive tract. A deficiency in IgA is common in patients with bronchitis, conjunctivitis and otitis media.
Other Randox assays that may be used to detect differing infections include: albumin, ferritin, alpha-1-antitrypsin (AAT), complement C3, complement C4, haptoglobin, CRP, alpha-1-acid glycoprotein (AGP) and anti-streptolysin (ASO).

Throughout the month of September, we will be highlighting on our social media channels how the Randox clinical range can help combat infections and infectious diseases through accurate and swift diagnosis, allowing the necessary steps to be taken in order to improve individual health.
What is infection?
Infection is the infiltration of an organism’s body tissues by disease-causing agents, their multiplication, and the reaction of host tissues to the infectious agents and toxins they produce. Infectious disease can also be known as communicable disease and transmissible disease.
How is the Randox helping to diagnose infection?
The Randox portfolio comprises of a wide range of products to combat infections including the RX series’ dedicated infectious disease testing panel, diagnostic reagents such as copper, potassium and sTfR and an extensive QC range catering for infectious disease testing in both liquid and lyophilised formats.
How can I limit my risk of contracting infection?
- The most important way to reduce the spread of infection is to wash your hands regularly with soap and water
- If you have an infection, get the appropriate vaccine and do not take antibiotics when they are not needed. This will only increase antibiotic-resistance
- Stay at home if you are sick to limit the spread of infection
- Use single-use tissues and dispose of them immediately after use
- Do not share cups, glasses or cutlery
- Do not touch your eyes, nose or mouth as viruses can transfer from your hands and in to the body
How can my workplace limit the spread of infection?
- Have an infection control plan
- Provide clean hand washing facilities
- Offer alcohol-based hand sanitisers when regular facilities are not available
- Provide boxes of single-use tissues and encourage their use
- Remind staff not to share cups, glasses or cutlery
- Remove newspapers and magazines from waiting areas
- Encourage staff to regularly disinfect their workspaces
- Make sure ventilation systems are working properly

Point of Care Testing (POCT) is the delivery of a test at the point in time at which the result will be used to make a decision and taking appropriate action resulting in an improved health outcome. It is also known as near patient, bed-side, extra-laboratory, decentralised, and ancillary testing . It has been shown to reduce hospital stay time, reduce complications, and improve adherence to treatment .
Point of care testing is not a recent practice; many early diagnostic tests were administered at the bedside. However, analytical technology has progressed and multiple tests can be performed within minutes in a laboratory. Recently, this technology has been put into the hands of the staff near the patients . There are two types of technology, benchtop analysers and hand held devices. Bench top systems are just smaller versions of laboratory analysers but some steps are automated. Hand held devices are simple in appearance but complex internally, they can manage several tasks including, adding reagents, separating cells from plasma, and reading colour or other measures.
Results can be obtained faster, allowing for more immediate decisions meaning treatment can begin sooner. Patients can live a longer and higher quality life, helped by a reduction in the length of hospital stays.
Some benefits of POCT :
The main objective of Point of Care Testing is to generate results more quickly so that appropriate treatment can be provided, resulting in an improved patient outcome.
Accurate and reliable results can only be obtained if the patient and sample are treated correctly. Point of care testing is likely to be performed by staff with a limited technical background, so training and quality control are vital.
Proper analysis technique alone is not enough to ensure an accurate decision; any test will only be beneficial if the appropriate action is taken based on the result. The effectiveness of POCT is assessed in terms of the overall outcome of the patient.
There are three phases in the POCT cycle: pre-analytical phase, analytical phase, and post-analytical phase. About 90% of quality issues are attributed to the pre-analytical and post-analytical phases . These errors are mainly attributed to user error and can be caused by a number of issues including, selecting the wrong POCT device, not following manufacturer instructions, inadequate training, not adhering to appropriate QC practices, and many more.
The errors can usually be mitigated by implementing an action plan and ensuring it is executed exactly as designed, deviation from the action plan will lead to errors. Errors in POCT diagnostics can lead to misdiagnosis, improper treatment, costly follow-up procedures, and death.
Some strategies for improvement:
Internal Quality Control and External Quality Assessment is conducted to monitor the stability of the analytical measurement system and to alert the operator to a change that may lead to a medically significant error .
A study by Price, Smith and Bruel  was conducted on a number of labs over a period of time of up to 15 years. They discovered that test result performance improved with time and was associated with regular participation in External Quality Assessment (EQA) schemes and with the use of internal quality control (IQC) procedures.
Internal Quality Control
Internal Quality Control (IQC) is used to assess the day-to-day consistency of assay performance, providing quality assurance for patient results. IQC activities are among the ten most common POCT deficiencies. These may include performing and documenting quality control testing and taking the correct action for outliers . This poor performance could be attributed to how IQC is viewed in POCT; users may lack appreciation of the potential for errors and may see the analyser as infallible, they likely see IQC as an additional workload as opposed to part of their testing routine.
CLSI regulations require risk assessment for each stage of patient testing alongside an implementation of a quality control plan. Below are some suggestions for how IQC should be conducted for POCT.
IQC should be conducted when: a new lot of consumable is used; a patient result is queried; after maintenance; the device has been physically insulted. IQC should be conducted by the usual device operator so assurance can be provided for the whole testing process.
ISO 22870 requires POCT users should be trained in the theory and practice of IQC . Staff should be trained in every aspect of POCT including storage, preparation, frequency, documentation and basic troubleshooting.
QC material for POCT should be obtained from a third party provider and not rely on material provided by the device manufacturer, the benefits of which are well documented. It should also contain analytes at clinically relevant concentrations, be provided ready-to-use, and be stable at ambient temperatures.
All IQC results must be recorded with the date, time, user, decision to accept or reject, and any actions taken as appropriate. Locally assigned ranges alongside analyte-specific rules should be used to maximise error detection. An example of how IQC could be recorded and an action flowchart can be seen in Fig. A below.
There should be a protocol for required actions following a failed IQC. Any troubleshooting should be developed with knowledge of the most common errors and user capability.
A monthly review should be conducted to identify persistent failures and trends.
The cost of IQC may also be a factor in resistance to IQC, however, while it is difficult to quantify, the cost of not conducting it may be greater in terms of human harm. A whitepaper is available detailing IQC in POCT (download).
External Quality Assessment
External Quality Assessment (EQA) or Proficiency Testing (PT) involves running blind patient-like samples and comparing your results to peer results, in order to retrospectively monitor the accuracy of reporting. EQA samples should be treated as if they were a patient sample and therefore must be run by personnel who would normally use the device. This provides confidence in the reliability of patient test results. (Learn more about EQA)
Benefits of participation in an EQA programme include assessment of result accuracy, assessment over time, comparisons with instruments, methods and peers, and providing confidence in test results.
EQA for POCT is, in theory, similar to EQA in a large laboratory. There is a significant difference however, the POCT participants are usually health care professionals with little knowledge of laboratory medicine. A lack of understanding of the importance of EQA had led to a smaller percentage of sites participating than large laboratories.
A Good EQA Scheme
A good EQA scheme should offer:
Conducting EQA in POCT
Below are some suggestions for how EQA should be conducted for POCT.
EQA samples should be commutable, meaning they have the same numeric relationship between measurements procedures as is observed for a panel of patient samples (reacts the same as a real patient sample).
A fast turnaround time allows test system errors to be identified sooner and necessary corrective actions to be taken immediately with minimum disruption to the lab.
A regular review of past EQA results should be part of the cycle of quality.
A POCT EQA provider should be able to provide assistance when the user is having difficulties.
Individuals carrying out testing should have the correct knowledge to interpret results, choosing a scheme with easy to interpret results can help.

Did you know that copper is an essential trace mineral present in all tissues? It works with iron to help the body form red blood cells. It also helps keep the blood vessels, nerves, immune system and bones healthy while also aiding in iron absorption. In rare situations, copper deficiency can occur and lead to anaemia and osteoporosis.
Symptoms of copper deficiency include:
- Fatigue & weakness as cells use copper to generate ATP, the body’s main source of energy. This means that copper deficiency could affect your energy levels.
- Frequent sickness as copper plays an important role in maintaining a healthy immune system.
- Weak and brittle bones as copper is involved in the processes that create cross-links inside your bones. These cross-links ensure bones are healthy and strong.
- Problems with memory and learning as copper plays an important role in brain function and development.
Sensitivity to cold as copper, along with minerals like zinc, help maintain optimal thyroid gland function. Low thyroid levels can make you feel colder more easily.
There are many foods that are high in copper. These include leafy greens, including turnip, greens, spinach, kale and mustard greens. Asparagus and summer squash are two other excellent sources of copper while legumes, whole grains, nuts and seeds are also good sources of the substance.
Randox Reagents, RX and QC are helping to diagnose copper deficiency at the earliest possible stage. The Randox copper assay is used to measure the levels of copper in the blood in order to determine copper toxicity. Combining this with the Randox zinc assay can aid in identifying the cause of liver damage in a patient, leading to correct treatment and recovery.
